Abstract

La présente invention concerne un système de terminaison câble modem (CMTS) doté d'une passerelle configurée pour produire des signaux sur des tunnels de données afin de les transférer, par l'intermédiaire d'un réseau câblé, à une installation d'abonné (CPE). Chaque tunnel de données se caractérise, de préférence, par un train de données unidirectionnel de signaux de messagerie hors bande (OOB).
